There are seven continents on Earth. Australia and Antarctica are entirely below the equator. Africa, Asia and South America are both above and below the equator.
Lima, the capital of Peru, is in South America, which is the Southern Hemisphere, and also the Western Hemisphere, which includes both American continents.
Earths crust extend deeper below the continents than below the oceans basins (or at least this is what I think).

South of the northern hemisphere is the southern hemisphere. There is no hemisphere "south of the western hemisphere" which extends to the South Pole. (East or west of the western is the eastern hemisphere.)
Argentina is in the Southern Hemisphere (below the equator) and the Western Hemisphere (west of Greenwich in the Americas).
The Western Hemisphere includes all of North, Central, and South America, the Caribbean, Greenland, and half of Antarctica. See the links below for maps of the hemispheres.
Only North America and Europe have no land in the southern hemisphere.Parts of Asia, Africa, and South America are below the equator, and the continents of Australia and Antarctica are completely in the southern hemisphere.
South America is in the Western Hemisphere and also in partially both the Northern and Southern Hemispheres. Africa is partially in the Western Hemisphere and too spans both the Northern and Southern Hemispheres.
The continents that lie only in the northern hemisphere are: entirety of Europe entirety of North America entirety of Central America the vast majority of Asia more than half of Africa, just below the "horn".
California
The second lowest point in the Western Hemisphere is the Laguna del Carbón in Argentina, which lies 344 feet below sea level.
